LibFrameFade is a World of Warcraft library that attempts to resolve UIFrameFade taint by reimplementing it to use the UI widget animation framework. This can help resolve issues such as "Interface action blocked by an addon" errors when attempting to perform actions such as joining battlegrounds or arenas in Classic Era or Burning Crusade Classic.
Note
As of recent versions of both Classic and Retail, the UIFrameFade framework has been patched by Blizzard and should no longer spread taint between unrelated UI functionality. As such, this library is no longer required and can be removed.
The design of the library is similar to LibChatAnims. You can either install it as a standalone addon, or embed it within another, and it will automatically manage UIFrameFade animations without any code changes required.
The library may be imported as an external in a .pkgmeta file as shown below, through the use of a Git submodule, or by downloading an existing packaged release and copying it into your addon folder.
